So, I've succeeded to export my data and edit it with PKHeX, I change the .sav extension into .dat when I export the main save with PKHeX.
No needed map file for my boot version.
svdt export from sd to savedata but when I launch the game, same problem... I think that's a problem with the file "SecureValue"...
Anyone can help me to allow me to play again on my 3DS with my save, please ?
Final Edit :
I remove the file « Secur Value » and everything works.
I’ve done all of that on last version of N3DS with OOTHAXX. I’ll try to explain step by step for newbie (like I was before).
